Class FileSystemStatusReporter

java.lang.Object

org.apache.tika.pipes.PipesReporter

org.apache.tika.pipes.reporters.fs.FileSystemStatusReporter

All Implemented Interfaces:

Closeable, AutoCloseable, Initializable

public class FileSystemStatusReporter
extends PipesReporter
implements Initializable

This is intended to write summary statistics to disk periodically. As of the 2.5.0 release, this is ALPHA version. There may be breaking changes in the future. Because invalid input: 'uses {@link java.time.Instant}, if you are deserializing with jackson-databind, you'll need to add jackson-datatype-jsr310. See the unit tests for how to deserialize AsyncStatus.'
